Fervit 10Gbps USB-C 5 Port SATA Adapter JMB575 JMS580

SKU CH-0AV1-6JK87

Connects five SATA drives via USB-C at 10 Gbps using dual JMB575 and JMS580 controllers

  • Connect up to five drives via a single USB-C port using cascaded JMB575 architecture
  • Achieve 10 Gbps host bandwidth through USB 3.1 Gen 2 JMS580 bridge controller
  • Operate drives on SATA 6 Gbps electrical specification 3.2 compliant links
  • Switch between command-based and FIS-based modes for flexible port-multiplier handling
  • Validate links with built-in BIST and loopback diagnostics

Five-Port SATA Adapter for USB-C Hosts

This adapter connects up to five SATA 3.0 drives to a single USB-C port using a JMB575 port multiplier and a JMS580 USB 3.1 Gen 2 bridge. The USB link runs at 10Gbps while each SATA channel operates at 6Gbps. It is built for users who want to access multiple 2.5-inch or 3.5-inch drives externally without installing an internal controller card.

Suits Multi-Drive External Storage Needs

It suits technicians cloning drives, photographers offloading several SATA SSDs or HDDs at once, and home-lab builders who need a compact, bus-powered JBOD enclosure alternative. Buyers who require bootable RAID arrays, hardware encryption offload, or internal PCIe add-in card form factors will not find those features here.

JMB575 Plus JMS580 Dual-Chip Architecture

The decisive specification is the combined JMB575 and JMS580 chipset that presents five independent SATA 6Gbps ports over one USB 3.1 Gen 2 10Gbps connection. This dual-chip design enables port-multiplier aware and non-aware host support plus command-based and FIS-based switching modes. If your workflow depends on a single-chip bridge or on internal SATA headers, this adapter is not the correct part.

Questions about this item

Should I use the five SATA 3.0 ports on the JMB575 chip or the single JMS580 bridge for my drives?

The JMB575 provides five independent SATA channels with port-multiplier support so you can attach up to five drives at once; the JMS580 bridges the whole array to the host over USB 3.1 Gen 2.

What real-world throughput can I expect from the 10Gbps USB 3.1 Gen 2 link when five SATA 3.0 drives are active?

The USB 3.1 Gen 2 connection caps at 10Gbps while each SATA 3.0 port runs at 6Gbps; simultaneous access to multiple drives shares the 10Gbps upstream bandwidth.

Does the USB 3.1 Gen 2 Type-C interface limit the 6Gbps SATA 3.0 ports in any way?

Yes — the single 10Gbps USB 3.1 Gen 2 upstream link is the bottleneck when several SATA 3.0 devices transfer data together.
